540Indiana I am surprised at how similar our experience has been. I bought my 98 540i last July and decided to dive in this Spring. Cooling a-z, valve cover gaskets (twice so far), plugs, CCV, etc.

Looking for a valve cover gasket DIY, I came accross this gem. Like I said, I have replaced and then had to reseal my VCG twice so far and now with this video I have a clear picture where I went wrong. I will now attempt this (thrice?)
